I'd checked compression days ago and now it hesistates. When I made 184 psi on cylinder three I realize that I didn't disconnect the power to the fuel pump or ground the coil wire as instructed by the manual, I quit. Now I'm haunted with a bad miss on cylinder three, cold or warm and sometimes stalling when put in gear. Both O2 sensors read 0.9V at 4K rpm and 0.3V when throttle releases, they're okay according to a service manual. Sparks aren't as bright.
I unplug the fuel injector connector number three, let it idle and no miss. I put connector back in, put in another spark plug and start the car and find a miss. Fully warm, I go for a drive, it hesitates. I open the hood, disconnect the cold start sensor (aka, coolant temp sensor) and everything is all fine. What could be wrong?
